Streptococcal adhesion to novel low-shrink silorane-based restorative.

摘要: Abstract Objectives The aim of the present study was to compare susceptibility one novel silorane-based and four widely used conventional methacrylate-based resin composites adhere oral streptococci relate any differences surface roughness, hydrophobicity type matrix. Methods Specimens restoratives Filtek Silorane, Z250, Tetric EvoCeram, Quixfil Spectrum TPH were prepared (10.0-mm diameter, 2.0-mm height). Surface roughness assessed by perthometer measurements according water contact angles determined computerized image analysis. Bacterial suspensions Streptococcus oralis , sanguinis gordonii mutans incubated for 2.5 h at 37 °C with 15 test specimens each material adhesion quantified fluorescence dye Alamar Blue/Resazurin an automated multi-detection reader. Glass served as reference. Statistical analysis performed using Mann–Whitney U -test ( α  = 0.05). Results Median values all ranged between 0.04 0.11 μm, median 59.7° 92.1°. Significantly lowest intensities materials found on Silorane three streptococcal strains. methacrylate significantly higher comparable among other. Significance When compared against composite resins, a general significance lower quantity adhering resin, which might result from its increased hydrophobicity. low potential may potentially improve longevity direct fillings reduce recurrent caries.
